Anyone see a problem with having kraft faced fiberglass insulation inside an interior wall?

Doing some bath remodeling. After removing the wall material in the bathroom, I noticed kraft faced batts were used in the wall. This wall is common to a loft bonus room. The wall in interior and the kraft side is facing the bathroom.

I suspect sound proofing was the thought vs insulating and the batts might have been extras from the attic insulation work. Would be easy to remove and replace if necessary.
